Related Material — 69.9% match
based on chemical composition and mechanical property overlap.
IS 6603 X01Ni31Cr27Mo4Cu (IS 6603:2024) and ASTM A959 317L (ASTM A959:2011) are both steel grades.
Both fall under the Stainless Steel category.
IS 6603 X01Ni31Cr27Mo4Cu is typically used for general purposes, semi-finished products, bars, wire rods and bright bars, while ASTM A959 317L is commonly used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1).
IS 6603 X01Ni31Cr27Mo4Cu is defined under Bureau of Indian Standards (IS), originating from India, while ASTM A959 317L is defined under ASTM International, originating from United States.
As per chemical composition, IS 6603 X01Ni31Cr27Mo4Cu vs ASTM A959 317L is a 70.6% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a related material overall at 69.9%.
